Hi, I installed binutils-2.9.1.0.19a as 'arm-aout' targetted.
When I assemble a simple example with arm-aout-asm, it
complains that
Error : Unknown pseudo-op '.section'
Error : Unknown pseudo-op '.previous'

When I look into the GAS manual, there exists the directive
'.section'. I can't figure out why this happens. Can anyone
explain this or advise?

Thank you for any kind or help or advice.

GAS only supports the .section pseudo-op when the target object format
supports sections. I don't think a.out supports sectioning, though.

JOOI - why are you trying to compile for arm-aout? The ARM port of Linux
supports ELF nowadays..

Nope, a.out has exactly three sections, .text, .data, and .bss. Given the
above messages, I assume you used -g and the compiler is now emitting dwarf
instead of stabs. You might try it with -gstabs+, since dwarf only works on
object files that support random sections, or as suggested use arm-elf.
